Abstract

The invention discloses an air-conditioning-based distribution network voltage regulation method, comprising the following steps: S10, performing power flow calculation, determining the state of the distribution network and the power P required for voltage regulation of each node of the distribution network 1 ,P 2 ,...,P n ; S20, according to the status of the distribution network, determine the working status of the air conditioner that needs to be switched to participate in the regulation; S30, screen the air conditioners that can participate in the regulation; S40, select the air conditioner that participates in the regulation according to the regulation priority; S50, update the room temperature and prepare for the next time adjust. The invention regulates the voltage of the distribution network through air-conditioning management to ensure the quality of electric energy.

Description

technical field [0001] The invention belongs to the field of power electronics, and in particular relates to an air-conditioning-based distribution network voltage regulation method. Background technique [0002] With the gradual transformation of my country's economic structure, the energy consumption structure has been significantly optimized, the quality of energy supply has been greatly improved, the achievements of energy technology innovation have been fruitful, the energy system has undergone profound changes, and the proportion of renewable energy in primary energy consumption has increased year by year. A "clean, low-carbon, safe and efficient" energy system will become a long-term goal. In the past 10 years, my country has become the world's largest investor in the field of renewable energy. In the 10 years to 2018, my country's wind power generation has increased by 22 times, and solar power has rapidly expanded by 700 times, which directly helped the global wind...
